Abstract
Ferrate has been observed under experimental conditions to be a potentially effective drinking water treatment chemical, serving as an oxidant, coagulant, and disinfectant. Although studies have ascertained ferrate’s potential to remove substances like bacteria, viruses, and organic matter, there is limited research for its use in mussel control and its synergy with other treatment methods. This research first explored ferrate’s ability to control dreissenids. Preliminary results from acute toxicity testing suggested that ferrate could be an effective alternative to chlorine in the inactivation of quagga and zebra mussel veligers. Additionally, veliger settlement tests showed similar performance between ferrate and chlorine. This work, however, was limited in scope, and would require future investigation. The research also explored the hypothesis that ferrate could enhance or inhibit the adsorption of geosmin by powdered activated carbon, through a series of jar tests. Overall, there was little observed impact of ferrate.
